Phys.org / A million new SpaceX satellites will destroy the night sky—for everyone on Earth
More than 10,000 Starlink satellites currently orbit Earth. We see them crawling across dark skies, no matter how remote our location, and streaking through images from research telescopes.
Phys.org / What's for dinner? Tooth enamel reveals what early Mesopotamians really ate
We can learn a great deal about the lives and social structures of civilizations thousands of years ago by studying what they ate. While actual food remains are few and far between, scientists can reconstruct ancient menus ...
Phys.org / Massive insect body size 300 million years ago may not have been due to high atmospheric oxygen
Three-hundred-million years ago, Earth was very different. The continents had coalesced into Pangea, which was dominated in its equatorial regions by vast coal-swamp forests. With high atmospheric oxygen levels, wildfires ...
Medical Xpress / Boosting good gut bacteria population through targeted interventions may slow cognitive decline
The origin of neurodegenerative diseases like Alzheimer's or dementia isn't limited to the brain. The state of your gut can quietly set off a cycle of chronic, system-wide inflammation that nudges the brain toward cognitive ...
Phys.org / Extreme global climate outcomes are possible even at 2°C warming, study warns
Extreme climate impacts on people and the environment are often associated with very high levels of global warming (3 or 4°C). A new study led by the Helmholtz Centre for Environmental Research (UFZ) shows that this assumption ...
Phys.org / Scientists solve 40-year-old biological mystery behind sleeping sickness
To survive in the human bloodstream, the African trypanosome parasite wears a "cloak" made of proteins known as a variant surface glycoprotein (VSG). The study, published in Nature Microbiology, identifies the protein that ...
Phys.org / Recovery from sudden permafrost collapse ranges from 10 years to a century, study suggests
Some Arctic regions regain their "greenness" within a decade of a sudden permafrost collapse, while others can take a century or more to recover, researchers report in a new study. The difference is directly related to each ...
Phys.org / JWST solves decades-long mystery about why Saturn appears to change its spin
Researchers at Northumbria University have used the most powerful space telescope ever built to answer one of the longest-standing puzzles in planetary science—why does Saturn appear to spin at a different speed depending ...
Phys.org / North Sea wind farms may be reshaping sediment flows by 1.5 million tons a year
Offshore wind farms are an important pillar of the European Union's strategy for renewable energy—by 2050, the EU aims to increase capacity in the North Sea more than tenfold. A new study by the Helmholtz-Zentrum Hereon shows ...
Phys.org / A universal scheme can verify any quantum state
Quantum technologies, devices that can process, store, or detect information leveraging quantum mechanical effects, could outperform classical devices in some tasks or scenarios. Despite their potential, verifying that these ...
Phys.org / Masripithecus: A new Miocene ape from Egypt sheds light on the origins of modern apes
In a study published in Science, an international research team from the Mansoura University Vertebrate Paleontology Center (Egypt) and the University of Southern California (U.S.) describe Masripithecus moghraensis, a newly ...
Phys.org / Embryo-like fossils from Southern China offer new clues about ancient life
Some of the most ancient fossils collected to date were traced back to the Ediacaran period. This is the time interval ranging from around 635 to 541 million years ago, shortly before the time when scientists predict that ...
